Tibia began as a school project by a few students at the University of Passau and they continued to develop the game afterwards. In the first few years they made several versions of the game but did not sufficiently maintain records of changes. In the process of leaving university they found a new host for the game servers and website and developed a new client. From version 6.0 and going forward they have maintained data regarding updates but anything that existed in-game before version 6.0 is considered "Pre-6.0".
